【摘要】 采用钛酸四丁酯为主要原料,以溶胶-凝胶法制备TiO2及不同Ag含量的Ag-TiO2,通过X射线衍射仪及傅里叶红外光谱仪对其结构进行必要的表征。以高压汞灯为光源,研究了TiO2及Ag-TiO2对甲基橙的光催化降解情况。结果表明,掺杂Ag+的TiO2对甲基橙的光催化降解效果较好。更多还原

【Abstract】 In this paper four butyl titanate is main raw material,prepared TiO2 and different Ag contents of the Ag-TiO2 by sol-gel method.By using X ray diffraction and Fu Liye infrared spectrometer its structure was characterized.Using a high pressure mercury lamp as light source,the initial concentration of methyl orange was degradated.The result indicated that the Ag+ doped TiO2 for methyl orange photocatalytic degradation effect is better than TiO2.更多还原
